Charles KWON OhJun adede5cd69 perf: REPLACE remove Flush + bulk build + deferred write = 1600x faster

Critical fix: REPLACE was calling area.Flush() after every field write!
- gengo gen_cmd.go: removed Flush() from emitReplaceCmd
- Harbour defers write until DBCOMMIT/CLOSE/GoTo, not per-REPLACE

Combined with bulk build + deferred APPEND:
- B1 APPEND 10K:  72,228ms → 30ms  (2,400x improvement!)
- B2 INDEX NAME:  34ms → 5ms       (6.8x improvement)
- Harbour comparison: Five 30ms vs Harbour 27ms (1.1x)

Also: OrderCreate flushes dirty record + EOF + header before index build
